硬度指数及脉搏波速度评估正常血压高值者外周动脉弹性阚艳敏马琳1刘洋刘水澎李建王艺桦华北理工大学附届医院超声科河北唐山063000【摘要】目的应用血管回声跟踪技术观察正常血压高值者颈动脉及股动脉弹性，探讨硬度指数（6）及单点脉搏波速度（PWV）评价外周动脉弹性的价值。方法二维超声测量正常血压高值组（76例）与正常对照组（50例）双侧颈动脉及股动脉内中膜厚度（IMT），并应用ET技术检测动脉漱PWV,对比分析两组参数；运用ROC分析法进行统计学分析。结果正常血压高值组的$PWV较正常对照组增高（P<0.001）,而两组问动脉内中膜厚度差异无统计学意义（P>0.05）;ROC分析显示颈动脉$PWV和股动脉$PWV的曲线下面积分别为0.762、0.861、0.778、0.891,以颈动脉67.45、PW^6.05m/林日股动脉67.55PW卬6.15m/s作为正常高值者外周动脉弹性异常的诊断界值时，敏感度与特异度均较高。结论正常血压高值者的外周动脉弹性在内中膜未出现形态学改变前已经降低，颈动脉67.45、PWV6.05m/sffl股动脉67.55PWV06.15m/S^够作为正常高值者外周动脉弹性异常的诊断界值，为临床防治提供客观依据。【关键词】外周动脉；动脉弹性；正常血压高值；血管回声跟踪技术EvaluationofperipheralarteryelasticityinprehypertensivepeoplebyandPWVKanYan-min,MaLin,LiuYang,LiuShui-peng,LiJian,WangYi-hua（DepartmentofUltrasound,AffiliatedHospitalofNorthChinaUniversityofScienceandTechnology,Tangshan,063000,China）Abstract:ObjectiveToobservethecarotidarteryandfemoralarteryelasticityinprehypertensivepeoplebyechotrackingtechnique（ET）,andinvestigatethevalueof6andPWV0inevaluationofperipheralarteryelasticity.MethodsBilateralcarotidarteryintima-mediathickness（IMT）wasmeasuredbytwo-dimensionalultrasoundin项目基金：河北省2014年度医学科学研究重点课题项目（编号ZD20140447）作者简介：阚艳敏（1977-）,女，硕士学位，副主任医师，研究方向：超声诊断学。E-mail:wuxiny_2009@163.com。通讯作者：马琳E-mail:malintsh@163.com76subjectswithprehypertensionand50subjectsofnormalcontrolgroup,usingETdetectedcarotidarteryelastic6andPW^,andtwosetsofparameterswerecomparativeanalyzed.ROCanalysiswasusedforstatisticalanalysis.ResultsComparedwiththenormalcontrolledgroup,andPWV^wereincreasedinsubjectswithprehypertension(P<0.001),IMTinthetwogroupsnosignificantdifference(P>0.05).ROCanalysisshowedthattheareaabou8andPW^ofcarotidarteryandfemoralarteryunderthecurverespectivelywere0.762,0.861,0.778,0.891,while67.45andPWV6.05m/sofcarotidartery,and07.55andPWV66.15m/soffemoralarteryasdiagnosisamputationvalueofcarotidarteryelasticanomalyinprehypertensivepeople,sensitivityandspecificitywerehigher.ConclusionsThecarotidarteryelasticityhavereducedbeforethearteryIMTdidnotappearmorphologicalchange,67.45andPWV6.---本文来源于网络，仅供参考，勿照抄，如有侵权请联系删除---05m/sofcarotidartery,and67.55andPWV66.15m/soffemoralarterycanbeusedasdiagnosisamputationvalueofanomalyperipheralarteryelasticityinprehypertensivepeople,andprovidingobjectivebasisforclinicalpreventionandtreatment.Keywords:peripheralartery;Arteryelasticity;prehypertension;Echotrackingtechnique正常血压高值是介丁原发性高血压与理想血压问的血压状态，即血压收缩压120〜139mmHgffi(或)舒张压80〜89mmHg［1］。目前，我国血压正常高值人群数量为高血压人群的一倍以上。与理想血压人群相比，血压处丁正常高值者更易发展为高血压，并发心脑血管疾病的风险增高，心脑血管疾病发生、发展的早期阶段血管即可出现损伤，血管功能受损的早期发现和及时修复对丁心脑血管疾病的防治有极为重要的作用［2］。本研究旨在应用血管回声跟踪技术(echotracking,ET)观察正常血压高值者颈动脉及股动脉弹性，探讨硬度指数(6)及单点脉搏波速度(P...
